POWER DRIVEN RAZOR Filed May 10, 1938 INVENTOR (04mm fla/vm/sn/vPatented Jan. 13, 1942 UNITED- STATES PATENT OFFICE f rowan 23; mzon IHoward Huntington, Stratford, Conn. Application May 10,1938, Serial No.2 os,9sc-

. 3 Claims. This invention relates'to power driven razors andparticularly to a type in which the hair cutting element is rotatedwithin a inder.

Its principal object is' to enable the user in a single device to shaverapidly and closely regardperforated cylless of the condition of hisbeard. It provides for ease of handling during the shaving operation,

freedom from vibration, long life and ready accessibility to all beardedsurfaces of the face.

The construction is such that the cutting toolis driven directly by themotor in the handle. The handle may be ellipsoid in shape. The

cutting head isof tubular formation,- perforated and in alignment withthe axis of the handle. The cutting tool contacts its inner surfacewhich, preferably, is eccentric to its outer surface. Thus long hairsmay thus be more readily clipped by holding the thicker walls to theface; the shorter hairs, by using the thinner side. On the thicker wallsof the head, especially, the holes are preferably of larger outside thaninside diameter or di mension, to permit the hairs more readily toapproach the smaller size openings at the inner surface.

The housing has a rounded end. This enables theuser to comfortably holdthe razor to portionsof his face that would not otherwise be soaccessible. The entire or greater part of the surface of the cylinderand a part of itsrounded end are perforated. The holes are preferably instaggered array thus presenting in a given stroke the maximumopportunity for cutting. To provide for long life the cutting portion ofthe rotating member may be an elongated blade fitting a longitudinalslot in the shaft. Two or more such blades may be provided. Thus, whenthe cutting edge of the blade or the inner wall of the cylinder I wears,the blade slips outwardly in its slot to maintain th desired contacttherebetween. Such a blade may also be arranged to slip longitudinallyto maintain contact at the rounded end.

In the drawing Fig. l is a general view of the head 5 of cylindricalshape. There is preferably one opening 6, or more, for the egress ofclipped hairs. Y

Over thegreater part of the head a multiplicity of perforations providefor the entrance of the hairs to .be cut. The outer end 8 is rounded andthe perforated area includes a portion of such .end. As shown theperforations are countersunk on the outside of the head or are otherwisemade larger in dimension than the openings 9 to theg The blades may liein longitudinal slots IQ of an integral or direct coupled extension llof the shaft 3. The lower ends I2 of such blades are bevelled to engagecorresponding bevelled surfaces it at the ends of the slots so thatunder centrifugal force the blades not only tend to move radially in theslots to press against the inner surface of the cylindrical part of thecutting head but also press longitudinally against the rounded end. Afurther force to press the blades laterallymay be supplied by springsifi-i i extending laterally through holes in the shaft H. The motorshaft 3, Fig. 2, drives the blade holding extension H by the engagementof a. tongue i5 on the former with a corresponding slot in the latter.Both the motor shaft 3 and the extension ll may be carried in ballbearing i'i. The motor 2 may be of the ordinary D. C.-A. 'C. type andcontrolled by a switch it at thebase of the handle. This switch has aflat bottom so that the razor, as a whole, will stand uprlght,' when notin use. When in use, a plug i9, Fig.1,

is inserted in the switch bottom to provide for an electric energysource through a conductor cord 26.

I claim:

1-. In a razor the combination of a handle, a

perforated head attached thereto havingatubular section and an endsection, a power shaft within the head having a longitudinal slot, and ablade conforming to said head carried by said shaft within said slot andradially slidable therein into contact with the tubular section of saidhead. one end of said blade "and the shaft at the corresponding end ofsaid slot having complemental bevelled surfaces adapted under theiniiuenee of centrifugal force to cam the blade longitudinally intoengagement with the end section 0! said head.

2. In a razor the combination of a handle, a perforated head attachedthereto having a tubuiar section and an end section, a blade within saidhead, and a power shaft having a bevel ended slot carrying said blade,said blade being movable radially in said slot under centrifugal forceinto contact with the tubular section of said head and terminating atone end in a camming mn'lace ccmplementinathe beveled end of said clotand adapted thereby to be pressed simulcombined surfaces.
